Abstract
A lighting device includes a light source, a light conducting plate having an incident surface receiving light emitted from the light source, a back surface and a light-emitting surface, and a reflection member having a first portion facing the back surface, and a second portion located on a side opposite to a side of the light conducting plate on which the light source is located. The second portion is spaced apart from the light conducting plate so that light emitted from the light conducting plate is oriented toward an emission surface of the lighting device.
